Go beyond what has been taught in Open Water! Choose from the various PADI specialty courses on offer. Increase your diving time with Enriched Air Nitrox or expand your dive limits with deep dives. There is certainly a specialty for you:

Deep dive
Nitrox
buoyancy control
Night dive
and many others …
Classes are held in Djerba and last between 1 or 2 days depending on the specialties chosen. You will become “specialist” in your chosen field, thanks to: your personal work, a theoretical course of your instructor, and dives at sea.
